Amazon paid $580 million in cash for Souq, according to filings. Bloomberg previously reported that Amazon was in discussions over an investment at a valuation in excess of $1 billion but, amid rivalry from Emaar’s ambitious Noon.com project and others, an acquisition agreement was reached.

The two companies said today that they have completed an initial integration that allows customers to log into Souq.com using their Amazon account credentials.

Next up, they plan to integrate products and services between the two sites to leverage their respective scale. In an announcement, Souq.com in particular spoke of the potential to integrate with Amazon’s global seller and customer base to boost its business.

“It is an exhilarating time for the e-commerce industry in the region. Together with Amazon, our goal is to offer our customers the widest product selection, great prices, improved delivery times and first-rate customer service,” Souq.com CEO and co-founder Ronaldo Mouchawar said in a statement.

Back to the Middle East, the Souq.com deal gives Amazon a firm footing in a growing and competitive e-commerce space. Souq.com itself claims over 45 million visitors per month and a range of 8.4 million products across 31 categories.

The region itself covers a total of some 50 million consumers across several countries, as well as a relatively untapped market: only about two percent of all retail spend today is made online, according to a report from McKinsey.

At the time of its confirmation, the deal was seen as an indicator that Amazon is prepared to buy its way into growth and new markets rather than simply relying on developing and expanding its own business. That point was later made all the more clear when, last month, Amazon announced its intention to acquire Whole Foods in a deal that is reportedly around the $13.7 billion mark.
